Patent FI-972873-A (FI)
Inventor: BANKS STEWART
IPC: B67D3/02
Filed: 1997-07-04
Abstract: A dispenser comprises a collapsible bottle and a valve assembly for placement in the throat of the bottle which includes a first hollow valve member sealed in the throat of the bottle and a hollow second valve member having apertures in the side wall. The second valve member telescopes in the first valve member between a closed position in which the apertures are located within the channel of the first valve member to close the bottle and an open position in which the apertures are in flow communication with the interior of the bottle. The first and second valve members are dimensioned to receive a probe forming part of a dispenser pump mechanism. The bottle is provided with crease lines located on the front, back and sides so that the bottle collapses as liquid is pumped out of the bottle to prevent exposure of the liquid contents to air.

Title: Electronic bistable circuit
IPC: H03K3/37
Filed: 1961-01-10
Abstract: 928,821. Pulse generating circuits. EBAUCHES S.A. Jan. 10, 1961 [Jan. 19, 1960], No. 1006/61. Class 40 (6). A pulse generating circuit comprises two or more electrode negative resistance devices connected in series and to a condenser, the arrangement being such that a first input pulse causes the condenser to charge through one negative resistance device and a second pulse at the same sign causes it to discharge through the other. Fig. 3 shows a capacitor C2 connected in series with a PNPN diode D1 across a voltage supply and in shunt with a further PNPN diode D2. Assuming the capacitor to be discharged, a triggering pulse applied to C3 and C4 will cause D1 to conduct and not D2 since the latter has zero voltage applied across it. The capacitor will charge through D1 until the voltage across the latter is insufficient to maintain conductivity when it will become non-conductive. The voltage across the second diode D2 is now such that when the next pulse is applied to C3 and C4 diode D2 will conduct and discharge the capacitor until the voltage is such that it extinguishes. Thus successive input pulses cause the diodes D1 and D2 to conduct for a short period alternately, a capacitor C 1 ensuring that only one is conducting at a time. Where positive triggering pulses are available these must be applied to the upper electrodes of the diodes (Fig. 4, not shown). Fig. 5 shows a similar circuit using two gas-filled valves. Valve V1 is connected in series with the capacitor C2 while V2 is in shunt with the capacitor. Again, assuming capacitor C2 to be discharged the triggering pulse applied to the grids from terminal E will render C1 conducting but not C2, conduction continuing until C2 is charged. The next pulse will cause V2 to conduct but not V1, the conduction in this case continuing until C2 is discharged.

Abstract: 584,634. Service hatches. GRIMSHAW, G. Jan. 12, 1945, Nos. 1067 and 5409. [Class 20 (iii)] Doors b, b' hinged at the respective ends of a service hatch are connected by links c, c' to a counterbalanced slider d movable in vertical guides e so that when either door is opened or closed the other is also opened or closed. In closing the doors, cams c<2> on the links c, c' enter between and pass under blade springs k, thereby assisting the closing and opening of the doors and holding them in the closed position.

Abstract: 455,136. Valves. WAGNER, F., 10, Bahnhofstrasse, Lichterfelde, Berlin. Jan. 14, 1935, No. 1267. [Class 135] In a balanced steam inlet valve in which an equalizing chamber 4 is connected to the livesteam space x by means of pipes 10 in the main valve 1 which have downwardly-extending openings 11 controlled by a throttling disc 12 on the spindle 5 of the auxiliary valve 6, an additional bore 13 is provided in each pipe 10 in axial alignment with its opening 11. These bores 13 which are smaller than the openings 11 prevent the formation of an unduly high lifting force as the disc 12 approaches the openings 11. To obviate the interference of the flow from the equalizing chamber 4 by the interaction of fluid streams on the axis of the passage 7, a guard ring 15 is provided on the main valve round the outlet of the auxiliary valve. A slot 16 is formed in this ring to prevent it acting as a suction nozzle on the chamber 4 and so causing the main valve to rise too suddenly.

Title: Improvements in and relating to the granulation of superphosphatic fertilisers
IPC: C05B19/02
Filed: 1948-01-15
Abstract: <PICT:0643762/III/1> A granular phosphatic fertilizer is made by forming a slurry of matured or partially matured superphosphate by adding moisture thereto prior to introduction into a conditioner and controlling the moisture content by introducing a moisture absorbing material into the slurry in the conditioner.  In one embodiment, superphosphate is conveyed (12) to a mixer 14 and sufficient water and/or ammoniacal liquor is added to form a slurry which is fed continuously to a conditioner 16 and mixed with fines (from the screening apparatus) or other moisture absorbent, e.g. powdered "den" superphosphate, sulphate of ammonia or potash or dried sewage matter, and if desired with other fertilizing salts. Granules from 16 are passed to a dryer-hardener 20 and thence to a screening apparatus. The process is applicable to the granulation of "den," double and triple superphosphates and to mixed fertilizers containing superphosphate, and may also be used where the process starts with rock phosphate and acid as given in another embodiment (Fig. 1, not shown) in which acid and rock phosphate are delivered to a mixer and the slurry therefrom is fed into a first conditioner, the granules from which are then reslurried in another mixer and the resulting slurry passed into a conditioner &c. as in the first embodiment. Specifications 559,482 and 625,863 are referred to.

Title: Glazing batting materials containing organic thermoplastic fibres
IPC: D04H1/54
Filed: 1952-01-22
Abstract: To the surface of a batting containing organic thermoplastic staple fibres interlaced and matted together, there is applied an aqueous solution or dispersion of a softening agent for the substance of the fibres, which softening agent has a boiling p  point above 125 DEG C., and the batting is then subjected to the action of a heated surface, whereby the fibres are coalesced at the surface of the batting and a glazed effect is produced.  The thermoplastic fibres may be of cellulose acetate, propionate, butyrate or other cellulose ester, or ethyl, benzyl or other cellulose ether, or of a polyamide, polyurethane, polytriazole or polyvinyl compound.  The thermoplastic fibres may be mixed with cotton, silk, wool, regenerated cellulose, jute, hemp, asbestos or other fibres.  The softening agent may be solid or liquid at ordinary room temperatures.  It may be glycerol diacetate, glycol diacetate, dimethoxy tetraethylene glycol, diethylene glycol monoethyl ether, acetyl acetone, triethyl phosphate, ethyl lactate, diethylene glycol, urea, acetamide, potassium thiocyanate, or boric acid.  The aqueous solution of softening agent may have a concentration of 5-20 per cent. by weight and may be applied so as to deposit 0.025-0.4 ounces of softening agent per square yard.  It may be applied by spraying to one or both surfaces of the batting.  The batting is subjected to the action of the heated surface before the applied aqueous solution of softening agent has had time to diffuse into the interior of the material. When the fibres are of cellulose acetate, the temperature of the heated surface is preferably between 120 DEG  and 150 DEG C.  The heated surface may be that of a press or calender roll.  In an example, a batting of cellulose acetate fibres is sprayed on one surface with an aqueous solution of glycol diacetate and immediately afterwards is contacted for three seconds and under a pressure of 2 pounds per square inch with a heating element maintained at 132-138 DEG C.  The batting becomes glazed uniformly at its surface.  It has a strong, flexible, porous surface and a firm coherent structure. Specification 608,753, [Group VIII], is referred to.
